  • Three-level to two-level decoder
    Patent number: 4097859
    Abstract: Improved three-level to binary decoding means for use in decoding a three-level digital data signal received from a transmission line in a serial digital data transmission channel. Uniform loading and controlled timing of the decoding are provided.
    Type: Grant
    Filed: November 1, 1976
    Date of Patent: June 27, 1978
    Assignee: Burroughs Corporation
    Inventor: Floyd William Looschen
  • Encoding and driving means for use in a three-level digital data communication system
    Patent number: 4084069
    Abstract: Improved encoding and driving means for use in a direct-coupled, three-level binary serial digital data transmission channel. The binary data to be transmitted is encoded into a three-level signal requiring only one transition per bit. A three-state balanced direct-coupled differential driving circuit comprised of dual differential amplifiers is used for driving the transmission line.

  • Receiving means for use in a digital data communication system
    Patent number: 4083010
    Abstract: An improved differential receiver circuit for use in a direct-coupled, binary serial digital data transmission channel. The receiver circuit comprises a pair of differential amplifiers having a cross-coupled biasing arrangement for providing thresholds for a received signal without degrading the high common mode capability and high impedance of the amplifiers.

  • Three-level serial digital data communication system
    Patent number: 4083005
    Abstract: A three-level, direct-coupled binary serial digital data transmission channel using a shielded twisted wire cable as the transmission line. The binary data to be transmitted is encoded into a self-clocking three-level code requiring only one transition for each bit transmitted. A balanced direct-coupled three-state differential driving circuit is used as the transmission line driver, and a balanced, direct-coupled three-level differential receiver circuit is used as the transmission line receiver.
